Complex tire query involving nested models

[rahul]

Hi guys,

I posted an issue in stackoverflow but it wasn't of any help.

Please take a look at http://stackoverflow.com/questions/17591034/complex-tire-query-involving-nested-models.

The original problem was to figure out how to search for authors having specific tags and who have written certain kind of books having specific tags.

I asked this question in IRC and @xeago suggested that nested mapping is the way to go. I looked up the nested mapping example in the tire repo.

Unfortunately my data isn't as simple as the models given in the example (posts, comments) - or maybe it actually is - I don't know because somewhere I am messing up the tire dsl

I tried something like this,

#inside author.rb
mapping do
  indexes :name, :type => 'string',
  indexes :tags, :properties => { :name { :type => 'string' } },
  indexes :books, :properties => { :type => 'nested', 
                           :book_type => { :type => 'string' }, 
                           :tags => { :name => { :type => 'string' }
                           }
end

# this is to build the datastructure for author
def to_indexed_json
  { :books => books.map(&to_document),
    :tags   => tags.map{ |t| { :name => t.name } },
    :name => name
  }.to_json
end


#inside book.rb
def to_document
   { :book_type => book_type,
     :tags   => tags.map{ |t| { :name => t.name } }
   }
end

What's happening is that the 'nested' property of books as defined in the mapping isn't being respected once Author.import is called and the data is indexed.

I have been stuck at this for 3 days :|

Thank you,

@rahul did you have a look at issue #56 ? is that similar to your problem?

@phoet I came across that issue before and should have paid more attention to it then. I sat down with it today and got it to work. Thank you for your suggestion.
